I adopted to my 48DCOE race motor, but this didn't work well. The head placed it too high and the front ear hit the hood. Complete setup, the 45DCOE plat was never used (i made my own for the 48's). Buyer will need to re-epoxy the cover to the base plate, and then good to go. only use on track 1 time. Buyer to pick up or pay the ride.
